Representation from the Boardroom to the Courtroom

Ogborn Mihm Quaintance, PLLC is a Sioux Falls, South Dakota law firm for business transactional, commercial litigation, personal injury, and legal malpractice matters.  Our lawyers have experience handling a spectrum of issues, from mergers and acquisitions, business entity issues, creditor’s rights, and real estate transactions to contract, company dispute, personal injury, and professional malpractice lawsuits.

What We Do

We assess, prepare, and present each case individually based on its unique facts and
circumstances; there is no template for the personalized representation we provide.

Our office provides hope for seriously injured people. We have the experience and the fortitude to fight for our client’s wellbeing and rights. Because this takes time and resources, we limit our representation to those clients who have serious injuries from a collision that have a significant impact on a person’s life.
